Chlorella and Spirulina are microalgae from green algae plants that contain substantial amounts of fatty acids (particularly polyunsaturated fatty acids), protein, chlorophyll, carotenoids, vitamins, including vitamin B12 and vitamin K, minerals, and unique pigments. Research shows daily dietary supplementation with chlorella may play a role in detoxification. One study showed microalgae supplemented in an enteral diet had significant protective effects on the intestinal mucosal barrier. Another clinical study suggests that fat metabolism and insulin signaling pathways could be physiologically supported by chlorella intake. Spirulina has antioxidant properties that can support healthy lipid metabolism and cardiovascular health.
